A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

Unlike traditional sensors, optical sensors use light. From aircraft to industrial systems, a sensing method is promising ...

When you’re designing miniature optical switches, reflective sensors are your best friend. They streamline the interaction between humans and machines in an elegant and intuitive manner. These sensors ...

New research has shown how the quantum mechanical principle of strong coupling opens unrivalled possibilities for designing optical filters. A team of researchers from the University of Cologne, ...

ROHM has developed the RPR-0730, an analogue compact optical sensor, capable of high-precision detection of fast-moving objects. This sensor can be widely utilised in consumer and industrial equipment ...

At some time or another, we’ve all had an idea we thought was so clever that we jumped on the Internet to see if somebody else had already come up with it. Most of the time, they have. But on the off ...

Understanding acoustic feedback in hearing aids. Power consumption challenges in hearing aids. Functionality integration and its impact on energy consumption. The benefits of using photoreflectors for ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

In-display fingerprint sensors have become commonplace in virtually all Android smartphones, for better or for worse, and five years later we’re finally seeing the ultrasonic variety widely used by ...
